3,053,293 DOOR MOUNTING MEANS Roland N. Nissen, Valley Center, Kans. Filed Dec. 4, 1958, Ser. No. 778,165 2 Claims. (Cl. 144-27) This invention relates to entryways. In a more specific aspect, this invention relates to doors and door frames, both interior and exterior doors. In still a more specific aspect, this invention relates to hanging interior and exterior doors in a door frame and on a jamb therein. Still more specifically, this invention relates to jig means having a frame mountable on a door or a jarnb therefor or on both, for guiding routing means during cutting of a hinge mortise in either the jamb or door or both, that is, in the latter instance routing the hinge mortise in the door and jamb in the same operation. In yet a more specific aspect, this invention relates to such jig frame means and in connection therewith an operative assembly to posi tion and maintain a jamb and door for routing of the hinge mortise in each in one operation.

The hanging of doors, both interior and exterior doors, is a tedious and time consuming job when done by the hand tool method and means known in the art, that is, using hand tools and no jig means to locate and cut out hinge mortises, etc. Complicated jig means for production door hanging in relatively large scale construction operations are known, but they are expensive, cumbersome and ineificient for use by the usual carpenter on the common and relatively small scale job, for example, in home construction and small office or other business buildings. The use of the jigs known in the prior art require auxiliary door and jamb handling means which is also expensive, cumbersome and inefficient for'the relatively small carpentry operations connected with house and other small building construction. I have invented new jig means for forming hinge mortises with routing means for mounting a door on a jamb with hinges, that overcomes all of the many difiiculties and disadvantages of the similar means known in the prior art. With the new jig means for forming hinge mortises of my invention, time consumed in the hanging of doors is greatly reduced, particularly the hanging of interior doors that require a full mortise cut-out (for the hinges. Thus, substantial labor cost is saved in hanging the doors. The new jig means of my invention for forming hinge mortises with routing means for mounting a door on a jamb with hinges i efficient in use, economical to make, and simple and compact in structure, making the new jig means of my invention particularly advantageous for use by carpenters on relatively small house and other building construction. Further, the new jig means of my invention is designed to work with the usual and standard routers which are commonly used to rout the hinge mortises in door edges and jambs.

The new jig means of my invention for forming-hinge mortises with routing means in the jamb and/ or door for mounting the door on the jarnb with hinges, has a frame which is removably mountable on the door alone to cut the hinge mortise therein, or on the jarnb alone, installed or not installed, to cut the hinge mortise therein, or on the door and jam-b at the same time to cut the hinge mortises therein in one operation. It is with the latter structure and method with which the new means of my invention has proven particularly advantageous. These frame means have means therewith which when mounted hold the frame on the door and/or jamb, holding the door and jamb firmly together when used in connection with both, and these holding means position the frame desirably to form the hinge mortises with routing means. The jig frame is constructed and operative when mounted 3,653,293 Patented Sept. 11, 1962 to guide the routing means to rout the jamh and/or door for mounting a hinge thereon.

It is an object of this invention to provide new means for building construction.

It is another object of this invention to provide new means for hanging doors, both interior and exterior doors.

Still another object of this invention is to provide new jig means for forming hinge mortises with routing means for mounting interior and exterior doors.

And, another object of this invention is to provide such jig means for forming the hinge mortises in a door jamb and door therefor in the same routing operation, or in the door alone, or in the jamb alone, and with the same routing means.

Still a further object of this invention is to provide new jig means for forming hinge mortises with routing means for mounting doors which is rapid, efiicient and easy to use, economical to manufacture and use, and structurally compact for easy use by carpenters in relatively small scale construction, such as housing, small ofiice buildings, other small business buildings, etc.

Other objects and advantages of the new jig means of my invention will become apparent to those skilled in the art upon reading this disclosure.

Drawings accompany and are a part of this disclosure. These drawings depict preferred specific embodiments of the new jig means of my invention for forming hinge mortises with routing means for mounting doors, and it is to be understood that such drawings are not to unduly limit the scope of my invention.

In the drawings,

FIG. 4 is a cross sectional view taken on line 4-4 of FIG. 3.

FIG. 5 is an enlarged perspective view of the iamb rest shown in FIG. 1 and mounted on the upper end of the door depicted therein.

Following is a discussion and description of. my new jig means for forming hinge mortises with routing means in doors and/or jambs therefor, either alone or when mounted together and in one operation. The discussion and description is made with reference to the drawings whereon the same reference numerals are used to-indicate the same or similar parts 'and/ or structure. Such discussion and description is of preferred specific embodiments of the new jig means of my invention, and it is to be understood that the discussion and description is not to unduly limit the scope of my invention.

Referring now to the drawings, FIGS. 1, 2, 4 and 5, the most preferred specific embodiment'of the new jig means of my invention is shown, and therein the jig means is used to form the hinge mortises with a common router (not shown) in a door and the jamb therefor at the same time and with the same routing operation. Also, the jig frame shown in these figures of the drawings is the same as that shown in FIG. 3 in a different use, that is, to form a hinge mortise in a mounted jamb in a doorway.

In using the new means of my'invention, the jamb sides in unmounted condition are cut to door length plus inch. One of these, the jamb side 7 on which the door is to be mounted is shown in the drawings, FIGS. 1 and 2. The usual and common jamb header, similar to that shown in FIG. 3 and given numeral 9, is cut to door width plus inch. This, of course, is preferred operation for interior door mounting, and allows inch at the bottom of the door when mounted, and /8 inch on the sides and the top when mounted. This sizing of the jamb sides and a jamb header is preferably done prior to the use of my jig means, and to prepare the jamb 7 for use therewith.

Next, prior to using the new jig means of my invention, a door 11 is selected, and preferably the top, bottom, hinge side, and inside face of the selected door is determined, that is, so that the grain of the wood, etc, will be that desired when the door has been hingedly mounted on jamb 7 and in the intended doorway.

The door 11 is properly supported on the edge of the lock or latch side, and with the hinge side 13 up. A door stand is preferably used to support the door 11 in the position of FIG. 1, and I have found it desirable to employ portable and collapsible door stand 15 depicted in FIG. 1, with the end 17 of door 11 supported in the grooves of the blocks 19 and 21 thereof.

A pair of jamb rests 23 of my invention are used, and they are mounted one in each end of door 11 in the manner shown in FIG. 1. These jamb rests 23 are removably mounted on door 11, and they have an outer portion 25 which projects outwardly from door 11 when the jamb rest 23 is mounted, and an integral inner portion 27 in which are formed sharp prongs 29, preferably by partially punching spaced triangular portions from the inner portion 27. Also, jamb rest 23 in the inner portion 27 has a head 31 formed therein which is used to position a jamb locator, as will be set forth hereinafter. The integral, one-piece jamb rest 23 is preferred. However, as one skilled in the art will realize, this jamb rest 23 can be formed with separate parts subsequently joined, if desired. The jamb rests 23 are mounted on the ends of doors 11 with the sharp prongs 29 inserted therein, and with the inner ends of portions 33 of outer portions 25 abutting against door 11, and in a position to hold and position jamb 7 flush with the edge 13 of door 11 and in aligned position with edge 13 for forming hinge mortises in jamb 7 and edge 13 of door 11 in one routing operation. This positioning is shown in FIG. 1 of the drawings. I have found it desirable to mount jamb rests 23 on the ends of door 11 by positioning the inner portion 27 properly relative to the end 17 of the door and then tapping the jamb rest with a hammer, driving the sharp prongs 29 thereinto.

When the jamb rests 23 have been mounted properly on door 11, the jamb 7 is layed thereon along the length of door 11, with jamb 7 face up and the jamb dado 35 slightly beyond the top end 17 of the door. This jamb dado 35 receives and mounts one end of the jamb header (not shown) when jamb 7 is mounted in the doorway wherein door 11 is to be hung.

A jamb locator 37 is used to longitudinally position jamb 7 stationary relative to door 11. A small section of channel iron has been found suitable for making jamb locator 37. The jamb locator 37 is removably inserted into the jamb dado 35, with the side of the locator in direct contact with inner portion 27 of the jamb rest 23, and with the end of jamb locator 37 in contact with bead portion 31. As will be seen by those skilled in the art, the thickness of jamb rest 23 inner portion 27 provides for clearance between the top end 17 of door 11 and the jamb header (not shown) when the door is subsequently mounted in its opening. With lighter gauge material for rest 23, bead 31 can be formed to provide this clearance.

With the jamb 7 in proper position relative to door 11, and supported by jamb rests 23 at each end of the door, and positioned by jamb locator 37 in jamb dado 35, the assembled hinge jig 40 of my invention is placed over the jamb 7 and door edge 13 of door 11 with the desired hinge size opening 42 formed by the jig frame 44 located over the door edge 13 and jamb 7. The jig frame 44 of jig means is preferably formed with another framed opening 46 which is for a hinge size commonly used to mount outside doors. The opening 42in frame 44 is for interior door hinge sizes, which are normally somewhat smaller than outside door hinges. Of course, any size openings 42 and 46 can be employed, as desired. Also, as can be seen, frame 44 can be constructed to provide openings 42 and 46 adjustable as to size.

The frame 44 of the jig has scribe lines 48 and 49 which are used to align the frame 44 relative to guide openings 42 and 46, respectively. For the interior door operation shown in FIGS. 1, 2, 4 and 5, the scribe lines 48 are aligned to the juncture line of jamb 7 and door 11 to position the frame laterally. This is done by adjusting the mounting and aligning screws 50 preferably threadedly and movably mounted in the end 57 of frame 44 on the jamb 7 side of the jig means. These adjusting screws 50 are preferably mounted in the end 57 of frame 44 with a nut 52 threadedly receiving same and with the nut 52 suitably mounted on the inside of frame 44, such as by welding nut 52 thereto. The inner ends of screws 50 are operatively mounted in a jaw 54, the inner face of jaw 54 engaging the edge of jamb 7 when the jig means 41) is mounted thereon (FIG. 1). Likewise, the other end 56 of frame 44 mounts screws 58, which are preferably secured therein by nuts 60 preferably welded to end 56 of frame 44 and threadedly receiving screw 58. The inner ends of screws 58 are operatively connected to the other jaw 62, the inner side of which engages door 11 when jig means 40 is mounted on the door (FIG. 1).

The new jig means of my invention for forming hinge mortises in jambs and/or doors has positioning rods 63 and 65 mounted in end 56 (FIG. 1) of the frame 44 to extend in each direction therefrom and substantially parallel to edge 13 of door 11. These positioning rods 63 and 65 are removably mountable in frame 44 and in either end 56 or 57 thereof. Holes 67 in the sides of the end portions 56 and 57 are provided to receive the rods 63 and 65, and a threaded collar 69 receives the inner ends of rods 63 and 65 to secure them end to end and in position extended through holes 67. Each of the rods 63 and 65 have a transverse outer end or hook portion 72 and 74, respectively, and when jig means 40 is mounted (FIG. 1), the portion 72 overlaps and contacts jamb rest 23 in the inner end portion 27 thereof to longitudinally position opening 42 in frame 44 of jig 40, so that the hinge mortises 75 and 77 will be formed in the proper place in jamb 7 and door edge 13 of door 11, respectively. A spring metal stop 80 is suitably secured to the underneath side of the top of the frame 44 to positively position rods 63 and 65, such stop 80 in operation abutting against the edge of threaded collar 69 which joins rods 63 and 65 to prevent movement of the rods.

The rod 63 (FIG. 1) in use is positioned to lock over jamb rest 23 in contact therewith, and this locates the upper hinge mortise in jamb 7 and door 13 the proper distance from the top end 17 of the door. Thus, rod 63 length is such as to provide for this, normally seven (7) inches from the top end 17 of door 11. With the positioning rod 63 in proper place, the thumb screws 58 on the door side end 56 of jig frame 44 are tightened, thus causing jaws 54 and 62 to firmly hold jamb 7 and door 11 together. A common router (not shown) is then moved over the top of frame 44 of hinge means 40 and guided by the template opening 42, and in routing operation the hinge mortises in door 11 and jamb 7 are formed with one setting and operation of the router. It has been found that this means provides for perfect alignment of the hinge mortises, and with greater speed and accuracy than can be accomplished with any means known in the prior art. Experience has taught to use a inch diameter follower, and a /8 inch diameter bit in the router. Of course, adjustment must be made for the depth of the hinge mortise, according to the thickness of hinge being used.

When the hinge mortises have been formed for receiving the top hinge for hanging door 11 on jamb 7, the hinge jig 40 is moved to the bottom end portion of door 11 and jamb 7, and the aligning and positioning procedure is again performed with jig means 40 to position for forming, the mortises for the bottom door hinge. For this purpose, positioning rod 65 is preferably made of such a length that when it is positioned with end portion 74 in contact with the other like jamb rest 23 mounted in the end of door 11 not shown, the jig frame 44 will be positioned to form the hinge mortises for the lower hinge eleven (11) inches from the bottom (not shown) of door 11. In this connection, it is advisable to point out that the aligning screws 50 operating jaw 54 on the jamb side and end 57 of jig frame 44 need not be moved after having originally been set for forming the mortises for the top hinge. The movable jaw 62 thumb screws 58 on the door side end 56 of jig frame 44 are simply loosened and ret-ightened, as repositioned by positioning rods 65. Of course, the hinge mortises for either the lower or upper door hinge can be formed first, followed by forming the other. The same router operation guided by opening 42 in jig frame 44 is performed to produce the lower hinge mortises in jamb 7 and door edge 13 of door 11.

When the mortises for both the upper and lower door hinge have been formed in the jamb 7 and door edge 13 of door 11, the hinge jig means 40 is removed from the jamb and door by loosening screws 50 and 58, and jaws 54 and 62, respectively, and the pre-cut jamb 7 and pre-cut door 11, with the hinge mortises 75 and 77, respectively, formed therein are moved slight-1y apart with the jamb 7 on the jamb rests 23. And, with them so slightly separated, the door hinges are installed on both the jamb 7 and door edge 13 of door 11. The square corners of the hinge butts are gently tapped to seat the hinges in the round corners of the hinge mortises, and it has been found that this results in a good fit of hinge in mortise. The jamb rests 23 and locator 37 are removed from the ends of door 11, and the jamb 7 is folded over door edge 13. In this position the usual jamb header (not shown) is installed in place in dado 35 of jamb 7. Preferably next, the door is inverted in stand 15 therefor, and the opposite jamb side (like jamb side 7) is installed on the jamb header. 1 have found in use that the latch cut-out in door 11 can be made at this time, if desired, but best results have been obtained by squaring and securing the jamb in place before installing the striker plate thereof. Withthe jamb sides and header joined and, the door hingedly mounted to jamb side 7, the now completed pre-hung door is installed in the rough door opening in the building. I have found that this is made easier by tacking the latch jamb side to the door approximately at latch location prior to installing the pre-hung door in the rough door opening. Also, shirnming and squaring the jamb to the door has proven very efficient and convenient when carried on by and with the means of my invention.

If desired, 1 have found that the new jig means 44) and rest means 23 of my invention can be efiiciently used to cut the hinge mortise in the door edge 13 separately, that is, free of the door jam-b 7. In this instance, a Wood block is used in place of jamb 7, so that the jig frame 40 can be properly mounted. Of course, the wood block used in place of jamb 7 must be of a size to properly receive jaw 54 of the jig means 40.

Likewise, the jamb 7 can be cut for the hinge mortise separately, that is, free from door 11, and in this instance, a block of wood of proper size can be used in place of door 11. The usual half surface butts can be installed in this manner, instead of the full mortises shown in the drawings for pre-cut doors.

The jig frame means 40 of my invention can also conveniently be used for making the hinge mortises in an exterior door frame or in installed interior jambs for full mortise hinges. FIG. 3 shows the new jig means of my invention used on a typical exterior door frame and jamb side thereof. In this operation the door (not shown) is cut and lit to the jamb or door frame which has previously been installed in the rough door opening in the building. In doing this it is preferable to allow A; inch clearance around the exterior door frame, and to install the threshold (not shown) before cutting the exterior door to its size. Also, it is preferable to insert a /8 inch block at the threshold of interior doors on the hinge side and to cut the door to size, allowing a As inch clearance around the door.

The hinge jig 40 is installed on such a jamb 90 with the desired opening 46 in the frame 44 over the rabbited portion )2 of the jamb 90 wherein the door is to be hung. Similarly for interior doors, this positioning would be over the hinge jamb side, and opening 42 in frame 44 would be placed so as to be over the portion of the jamb desirable to have the mortises for the hinges. The positioning rod 63 (FIG. 3) is positioned to contact the bottom of jamb header f with the transverse portion 72 of the rod, and with rod 63 in fully retracted position. The scribe lines 48 are aligned to the edges of the jamb 90 shown (FIG. 3), by adjusting the two aligning thumb screws 58 on the back or end 56 of hinge jig 40. With proper alignment, the thumb screws 56 are tightened on the door side or end 57 of hinge jig 40. The jaws 62 and 64 then engage the edge of jamb W and outside door casing 95, respectively, to clamp the hinge jig 40 in proper position.

The router (not shown) is properly adjusted, as before, and guided by opening 46 in frame 44 of jig means 40, it is used to form the hinge mortise in poition 92 of jamb 90, and adjacent the stop portion 98 thereof. The hinge jig 46 is then removed by loosening screws 50 and jaw 54 from the edge of the jamb, and the jig is moved and re-installed at the bottom end portion of jamb 90, with positioning rod 65 and the transverse end portion 74 thereof just touching the threshold (or block therefor). Screws 50 and the jaw means 54 are then retightened and the mortise for the lower hinge is cut out of portion 92 of the jamb 90. With the lower hinge mortise cut out, the hinge jig 40 is removed from jamb 90.

The door to be mounted on jamb 90 is then placed on edge with the hinge side up (as FIG. 1), and preferably supported by a door stand such as stand 15. In the manner discussed hereinbefore and shown in FIG. 1, the hinge mortises are cut in the hinge edge of the door, preferably using a block of wood in place of the jamb 90 which has been installed. The block of wood representing the jamb should be the same width as the jamb. It has been found that this works well, providing the correct spacing, and also preventing the usual splintering or chipping of the door when the hinge mortise is cut therein. With the hinge mortises cut in the door and previously in the jamb 96, the hinges (not shown) are installed in the usual manner and the door hung on jarnb 90.

The jig means 40* and jamb rests 23 of my invention can be formed of any suitable material by any suitable means. I prefer that they be made of cold rolled steel, preferably cadmium plated throughout. If desired, forged aluminum, or die cast aluminum can be used with steel screws 50 and 58, and nuts 52 and 60 therefor, respectively. The jamb rests 23 are preferably made in the one-piece construction shown in FIG. 5, and most desirably of cadmium plated cold rolled steel. This provides for long life of the jamb rests.

As will be evident and obvious to those skilled in the art, various modifications of the new jig means of my invention can be made, or followed, in the light of this disclosure and discussion, without departing from the spirit or scope of the disclosure, or from the scope of the claims.
